CHINO HILLS - City officials have been unable to confirm if another Chinese maternity hotel is operating in the city out of a mansion in the Grand Pointe community.

The accusation was levied last week at a community meeting hosted by the Not in Chino Hills grassroots group. A speaker said a mansion in the gated neighborhood has been used to house pregnant Chinese woman who are visiting the United States to have children on American soil.

Law enforcement and city officials have confirmed that wealthy Chinese women have been staying at the home at 15250 Woodglen Drive as well as Green Valley Apartments at 14901 Frost Ave. until they give birth at area hospitals.

Not in Chino Hills spokeswoman Rossana Mitchell said a complaint was filed with the city against the Grand Pointe mansion.

The president of the Grand Pointe homeowners association has asked to handle the matter privately with the city, said Mitchell, who is running for a seat on the Chino Hills City Council in March.

"It's a gated community and we have to respect that," she said. "That individual in Chino Hills did file a complaint, and I understand that the city is looking at it."

City Manager Mike Fleager said he wouldn't want to comment on the alleged third location.

"If a complaint comes in, we will investigate it as we do with all code cases," Fleager said.

"Any legitimate code violation that is reported, the city investigates and we would do the same with another report of another hotel, just as we did with the original complaint. That's the process."

City officials said they are also in the process of filing a criminal complaint against Hai Yong Wu, the owner of the 7,964-square-foot Woodglen Drive house, because of several code enforcement violations.

Wu allegedly violated ordinances against operating what the city considers a hotel in a residential house and against altering the structure of the house without permits, City Attorney Mark Hensley said.

The seven bedroom, six-and-a-half bathroom home is built on 10-acres.

As of Monday, no complaint has been filed against the Woodglen homeowner, city officials said.

Calls made to Wu's translator as well as the three phone numbers listed on a gate at the Woodglen home on Monday were not returned.

No charges have been filed against Green Valley Apartments, which is owned by Lewis Operating Corp.

"We'll continue looking into this and we will cooperate with the city of Chino Hills," said Randall Lewis, executive vice president of Lewis Operating Corp.

Not in Chino Hills members said their mission is to preserve the city as a family-oriented community.

"We want to continue to enjoy our beautiful city and we welcome everyone, but, to preserve what we cherish, we must also protect our city," the group's website says.

Mitchell also said there is a nearby medical clinic where a luxury van has dropped off and picked up the pregnant women.

"We're not going to disclose location but we're going to do some follow up on that," she said.

"We want to follow though, confirm it and make sure it's accurate, and get our confirmation. There's ways to do that just by going down there."

Members from the grassroots group will attend tonight's council meeting at 7 at the City Council Chambers, 14000 City Center Drive.
